Rheological additives for asphalt and other organic systems comprising one or more organoclays and fibrous material, a process for producing such additives and organic systems containing such additives

摘要

The present invention involves the discovery that an organoclay made by the reaction of smectite day and a quaternary ammonium compound (quat) can be mixed with fibrous material such as wastepaper pulp to form a unique theological additive for organic fluid systems. Such a theological additive has broad uses, is cost effective, and is particularly useful as a rheological additive for asphalt and organic paints and coatings. In an important aspect the invention is a rheological additive providing inexpensive, effective and efficient rheological properties when used at low levels in organic systems.
